H. P. JUDSON, OF BETHLEHEM, CONNECTICUT.

OX-YOKE.

Specification of Letters Patent No. 26,191, dated November 22, 1859.

To all whom it may concern:

Be it known that I, H. P. J UDSON, of Bethlehem, in the county ofLitchfield and State of Connecticut, have invented a new and usefulSelf-Locking Bolt for OX-Yokes; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, in which Figure 1, represents a perspective View of onebow attached to the yoke-beam. Fig. 2, is a side View of the plate andlocking device showing the manner of making the bolts self-locking. Fig.3, is an under side view showing clearly the device for locking andunlocking the bow from the beam, the parts being represented in twopositions.

The nature of my invention and improvement in self-locking bolts for OXyokes consists in a novel combination of a rotary spring disk, curvedand horizontally moving bolts, arranged and operating as hereinaftershown.

To enable others skilled in the art, to which my invention pertains tounderstand it, I will proceed to describe its construction andoperation.

By a reference to Fig. 3, my invention is exhibited applied to one halfof the yoke beam and the several parts to be described is clearly shownby the enlarged figures in detail, to which I will have reference in thefollowing description.

A represents a plate inclosing the parts for actuating the two bolts B,B, which play in guards C, C, which may be cast with the plate A. In thecenter of this plate is a hole, through which passes the pointed end ofthe bow. This hole is sufficiently large to admit the end of the bowwhich is These bolts B, B, are in the same axial line, and approach, andrecede from each other simultaneously, meeting in, or near the center ofthe circular opening in plate A, and consequently in the center of thestem of the bow, when inserted therein.

The operation of the bolts is eflected by the following device: Byreference to Fig.

3, which shows the bottom of the plate A, D, is a rotary disk containinga colled flat spring which is indicated by red lines. This disk D, whichis recessed in the plate A, has a square stem passing through it and towhich is attached a knob E, shown in Fig. 2; on the outside of the plateA is a curved rod F which is pivoted to one side of the disk D, andpasses to the bolt B, to which it is connected by a pivot joint G.

Gr, is a shorter rod which is also pivoted to the disk D, but connectswith the bolt B. These connections are so made that the action of thespring upon both the bolts is simultaneous, and by turning the thumbpiece or knob E, the bolts will both be opened as represented by Fig. 3,and indicated by red lines.

One end of the bow J, is tapered on each side up to a point, as clearlyshown by Fig. 2, the taper commencing just above the bolt hole K, whichhole passes through the end of the bow and is sufficiently large toadmit the bolts to enter readily. The object of thus tapering the end ofthe bow is to effect the self locking principle and by beveling the endsof each bolt, as shown by Figs. 2, and 3, the pointed bow will act likea wedge in pressing it between the ends of the bolts, and thus open thebolts and allow the end of the bow to enter the hole in the beam untilthe hole K, is opposite the ends of the bolts, when they willsimultaneously spring into it, and lock the bow to the yoke beam.

The yoking up of cattle with this device applied is rendered verysimple, and can be accomplished with great rapidity while at the sametime the device is simple, strong and durable.

\Vhat I claim as my invention and desire to secure by Letters Patent is,

The arrangement of the peculiar rotary sprin disk D, curved rods F, G,and horizonta 1y moving locking bolts B, B, as and for the purposeherein shown and described.

H. P. J UDSON.
